Preheat oven to 350 degrees. Line a cookie sheet with parchment paper.
Carefully unroll the crescent rolls, being sure to keep them in a rectangle. Do not separate them; press together the seams of all 8 rolls to form a large rectangle.
Spread with a small amount of butter (light butter spread is fine too).
Mix granulated sugar, cinnamon and orange zest in a small bowl. Sprinkle evenly over the rectangle of dough, being sure to go right up to the edges. Sprinkle with the chocolate chips.
Starting at the short end, tightly roll the crescent rolls back into a roll, pressing together seams as needed. Slice into 8 equal sized pieces and place on prepared cookie sheet.
Bake for about 10 minutes, until browned.
Prepare glaze while they are baking. Whisk melted butter, powdered sugar and orange juice in a small bowl. Drizzle onto hot rolls when the come out of the oven. Rolls are best warm.
